Build a Marketing Team in ChatGPT
Research to Content on Autopilot
You can now build a complete, automated digital marketing team inside ChatGPT. It’s an absolute powerhouse.
I’ve been using ChatGPT for all sorts of tasks, but my results for big projects often felt disconnected, a blog post here, a social media idea there. I just stumbled upon a video from a sharp AI professional who lays out a complete, end-to-end system that finally connects all the dots.

The mind behind it has created a workflow that transforms ChatGPT from a simple assistant into a full-fledged, strategic marketing engine.
What really blew me away is the core idea: stop thinking in features and start thinking in systems. Instead of one-off tasks, the creator shows how to build a process where each step logically feeds into the next. It starts with deep research, which then informs your core strategy, which then fuels all your content creation, and is finally scaled through automation.
Everything is perfectly organized and on-brand, every single time. It’s one of the smartest setups I’ve seen.
The Full Workflow Breakdown
The entire process is built around turning raw data into a self-sustaining marketing machine. The creator demonstrates it with a sample brand, but you could apply this to literally any business.
Build the “AI Brain” with Projects & Deep Research
This is the foundation, and it’s brilliant. The creator doesn’t just start asking questions. First, they set up a dedicated “Project” in ChatGPT, which acts as a central workspace for the entire marketing team. Into this project, they upload a basic brand overview document. Then, they add a custom instruction telling ChatGPT to act as the “marketing team lead” and to always structure its outputs for clarity.
With that context in place, they trigger a Deep Research task. But the prompt isn’t just “research my audience.” It’s super specific, asking for:
Digital behaviors and channel preferences
Key pain points and desires
Content gaps and competitor weaknesses
Purchase decision factors
Because this runs inside the Project, the research is automatically framed by the brand’s context. The result is a massive, comprehensive report, the creator got a report citing 24 sources, that becomes the “brain” of the entire operation. You then export this report, because you’re about to feed it right back into the system.
Turn Raw Data into Actionable Strategy
Data is useless without a plan. In this next phase, the creator uploads the Deep Research report back into the same Project. Now, ChatGPT has both the original brand info and a deep understanding of the market. The creator then prompts it to generate three key strategic documents:
Customer Personas: Based on the research, it builds out detailed personas. The video shows ChatGPT creating three distinct customer profiles, complete with demographics, values, pain points, and even their preferred content types. These aren’t just generic personas; they’re directly derived from the research data.
Digital Marketing Strategy: Using Canvas mode (ChatGPT’s collaborative editor), the expert asks for a full digital marketing strategy. Canvas is great here because it lets you edit the output like a Google Doc. The AI drafts a complete plan, outlining business objectives, brand positioning, and which channels to prioritize, all while referencing the project files.
Brand Voice & Channel Guidelines: Finally, they generate a detailed brand voice guide. This includes tone variations for different channels (like Instagram vs. Pinterest), a messaging hierarchy for each persona, and even a list of “do’s and don’ts” with examples. This document ensures every piece of content will sound consistent.
At the end of this stage, you have a Project loaded with your brand overview, deep market research, customer personas, a marketing strategy, and brand voice guidelines. The AI is now a true subject matter expert on your brand.

Scale & Automate Your Content Engine
This is where it all pays off. With the strategic foundation built, the creator shows how you can generate a flood of on-brand content for a campaign. For a “back-to-school” campaign, they simply ask for a 1000-word blog post. They don’t have to specify the tone or audience, because ChatGPT already knows everything from the project files. The expert notes the content quality is fantastic and speaks directly to the target persona.
It gets better. They then generate visuals by connecting ChatGPT to a Google Drive folder containing brand style references and ask it to create a hero image and mood shots for the blog. From there, they generate Pinterest posts, Instagram carousel copy, and even an email sequence, all perfectly aligned with the strategy.
To scale this for a human team, the creator packages the whole system into a Custom GPT. They upload all the strategy documents into the Custom GPT’s knowledge base and share the link with their team.
Now, anyone on the team can use this specialized GPT to create on-brand content without needing access to the original Project. Finally, they set up an automated Task that runs every Wednesday.
The task prompts ChatGPT to find trending topics, analyze how they relate to the brand’s personas, and draft ready-to-publish social media posts. The system finds ideas and creates content for you on autopilot.
This workflow is an incredibly thoughtful way to use AI to build a scalable, efficient, and consistent marketing process. It’s a must-watch for any marketer trying to get more from these tools.
